NANO FLEX 2 BIBSHORT
RIDE THROUGH ANYTHING
In dry conditions our Nano Flex fabric is stretchy, breathable and warm thanks to its softly fleeced inner face. But in wet conditions the nanotechnology water-repellent surface keeps much of the moisture at bay. There is no membrane to block breathability, though, so in harder rain or on longer rides some moisture will come through. But that’s when this fabric is at its best: it never feels waterlogged, it almost feels dry on your legs and, best of all, it continues to keep you warm.
KISS Air² seat pad for all-day comfort
Affinity Spandex fabric on inside of leg for outstanding stretch and rebound
Affinity BLC textured fabric on legs for better aerodynamics
GIRO Air engineered mesh gripper
Reflective detailing on back
- Mesh straps for comfort and breath ability
If you’re going to do serious rain riding, you should look to our Nano Flex Pro 2 Bib Short, or even the Tempesta Pant, but for lighter rain, warmer temps or wet roads this will be ideal.

Muscle Support and Speed
In re-engineering the Free we took a look at blood flow, providing just the right muscle support without constricting. The revolutionary Giro Air leg band provides more stretch and distributes the compression over a larger area. The body of the short uses Spandex for excellent return.
We also looked at aerodynamics, optimizing boundary-layer airflow with the Giro Air leg band and the dimples on the side fabric. The wind tunnel says it saves 10 watts at 50 km/h, but you’ll probably want to go even faster because your aero advantage will only increase.
Confort and Fit
The best race short must be supremely comfortable. The new fabrics are all softer than the outgoing fabrics, especially the new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach. And we’ve engineered a new Carré yoke that makes the straps lie perfectly flat.
But the most important part of comfort is fit. As one of our pro testers said, “These shorts fit perfectly. They don’t move around. Everything is just right.”
The Castelli Nanoflex 2 Bibshort - Black is a sensational customer favorite, and we hope you like it just as much.
